Description

풀림방지 볼트조립체{LOOSING PREVENTION BOLT ASSEMBLY}[0001] LOOSING PREVENTION BOLT ASSEMBLY [0002]

본 발명은 풀림방지 볼트조립체에 관한 것으로서, 보다 자세하게는 장기간 안정적인 풀림방지 효과를 제공할 수 있는 풀림방지 볼트조립체에 관한 것이다. The present invention relates to an anti-loose bolt assembly, and more particularly, to an anti-loose bolt assembly capable of providing a stable anti-loosening effect for a long period of time.

볼트와 너트는 나사결합에 의해 체결력을 유지하는 체결요소로서 오래전부터 다양한 분야에 널리 사용되고 있다. 그러나, 볼트와 너트는 암나사와 수나사 사이의 마찰력에 의해 체결력이 유지되므로, 충격과 진동에 의해 쉽게 풀어지는 단점이 있다. Bolts and nuts are fastening elements that retain the fastening force by screwing and have been widely used in various fields for a long time. However, since the fastening force is maintained by the frictional force between the female screw and the male screw, the bolt and the nut are easily disassembled by shock and vibration.

이에 볼트와 너트의 체결이후 풀림을 방지하기 위한 다양한 구조가 연구되고 있다. 일례로, 한국공개특허공보 제10-1999-0019896호에 볼트와 홈붙이 너트의 풀림방지구조가 개시된 바 있다. 개시된 구조는 다수개의 고정홈이 방사형으로 형성된 홈붙이 너트와, 그 홈붙이 너트의 고정홈에 안착되는 복수개의 고정발이 돌출 형성된 볼트를 포함한다. 이 구조는 볼트 끝단에 연장형성된 고정발의 가공이 어려우며, 체결 후 고정발을 일일이 절곡시켜주어야 하므로 작업공수와 작업시간이 지연되는 문제가 있다. Therefore, various structures are being studied to prevent loosening after fastening of bolts and nuts. For example, Korean Unexamined Patent Application Publication No. 10-1999-0019896 discloses a structure for preventing loosening of bolts and slotted nuts. The disclosed structure includes a grooved nut having a plurality of fixing grooves radially formed therein, and a plurality of bolts protruding from the fixing grooves that are seated in the fixing grooves of the grooved nut. In this structure, it is difficult to process the fixed leg formed at the end of the bolt, and since the fixed foot must be bent after fastening, there is a problem that the work flow and the working time are delayed.

이 외에도 다양한 풀림방지 볼트가 현출된 바 있으나, 그 구조가 복잡하여 제작 및 사용이 불편하고 시간이 경과함에 따라 풀림방지 효과가 점점 줄어드는 결점이 있다.

여기서, 결합돌기(120)는 볼트머리(110)의 원주방향을 따라 경사면(121)과 수직면(123)이 반복되는 형태로 형성된다. 이 때, 경사면(121)은 낮은단부(121a)가 볼트(100)의 체결방향으로 향하고, 높은단부(121b)가 볼트(100)의 풀림방향을 향하도록 형성된다.Here, the engaging projection 120 is formed such that the inclined surface 121 and the vertical surface 123 are repeated along the circumferential direction of the bolt head 110. At this time, the inclined surface 121 is formed such that the lower end portion 121a is directed toward the fastening direction of the bolt 100, and the higher end portion 121b is directed toward the releasing direction of the bolt 100. [

수직면(123)은 이웃하는 경사면(121) 사이의 단차를 수직하게 연결한다. 수직면(123)은 와셔(300)의 걸림수직면(333)과 접촉되며 걸림결합되어 볼트(100)와 고정너트(N)의 체결시 볼트(100)와 와셔(300)가 함께 회전되게 한다.The vertical surface 123 vertically connects the step between the adjacent inclined surfaces 121. The vertical surface 123 is in contact with and engaged with the engagement vertical surface 333 of the washer 300 so that the bolt 100 and the washer 300 are rotated together when the bolt 100 and the fixing nut N are fastened.

볼트축(130)은 볼트머리(110)의 하부로부터 수직하게 일정 길이 연장된다. 볼트축(130)의 외주연에는 제1나사산(140)이 형성된다.
The bolt shaft 130 extends vertically from the bottom of the bolt head 110 by a predetermined length. A first screw thread 140 is formed on the outer circumference of the bolt shaft 130.

와셔(300)는 볼트(100)와 체결대상(M) 사이에 삽입되어 볼트(100)와 고정너트(N)의 구속상태가 유지되도록 한다. 한편, 고정너트(N)는 제1나사산(140)에 대응되는 제2나사산(미도시)이 내부에 형성된 구조물일 수 있다. 그리고, 와셔(300)는 볼트머리(110)의 하부와 맞닿게 배치된다. The washer 300 is inserted between the bolt 100 and the fastening object M so that the restraint state of the bolt 100 and the fixing nut N is maintained. Meanwhile, the fixing nut N may be a structure having a second screw thread (not shown) corresponding to the first screw thread 140 therein. The washer 300 is disposed so as to abut the lower portion of the bolt head 110.

와셔(300)는 도 3에 도시된 바와 같이 와셔본체(310)와, 와셔본체(310)의 상면에 돌출형성된 걸림돌기(330)와, 와셔본체(310)에 관통형성되어 볼트축(130)이 삽입되는 축삽입공(320)과, 와셔본체(310)의 축삽입공(320)의 둘레방향을 따라 관통형성된 삽입홈(340)과, 삽입홈(340)에 삽입되는 자력부재(350)를 포함한다. 3, the washer 300 includes a washer main body 310, an engaging protrusion 330 protruding from the upper surface of the washer main body 310, a bolt shaft 130 formed through the washer main body 310, An insertion groove 340 formed to extend along the circumferential direction of the shaft insertion hole 320 of the washer main body 310 and a magnetic force member 350 inserted into the insertion groove 340. [ .

걸림돌기(330)는 와셔본체(310)의 상면으로부터 경사지게 상방향으로 돌출형성된다. 걸림돌기(330)는 걸림경사면(331)과, 이웃하는 걸림경사면(331)을 수직하게 연결하는 걸림수직면(333)을 포함한다. The locking protrusion 330 protrudes upward from the upper surface of the washer main body 310 in an inclined manner. The hooking protrusion 330 includes a hooking inclined face 331 and a hooking vertical face 333 connecting the adjacent hooking inclined face 331 vertically.

걸림돌기(330)는 볼트머리(110)의 결합돌기(120)와 대응되는 형상으로 형성된다. 이에 의해 볼트(100)가 고정너트(N)와 체결되었을 때, 걸림돌기(330)는 결합돌기(120)와 맞닿고 수직면(123)과 걸림수직면(333)이 서로 접촉하여 걸림결합된다. The engaging protrusion 330 is formed in a shape corresponding to the engaging projection 120 of the bolt head 110. When the bolt 100 is fastened to the fixing nut N, the locking protrusion 330 abuts against the engaging protrusion 120 and the vertical surface 123 and the engaging vertical surface 333 are engaged with each other.

여기서, 걸림경사면(331)의 높은단부(331b)는 볼트(100)의 풀림방향을 향하고, 걸림경사면(331)의 낮은단부(331a)는 볼트(100)의 체결방향을 향하도록 형성된다.
Here, the high end 331b of the locking slope 331 is directed toward the releasing direction of the bolt 100, and the low end 331a of the locking slope 331 is directed toward the fastening direction of the bolt 100.

삽입홈(340)은 자력부재(350)를 내부에 수용한다. 삽입홈(340)은 와셔본체(310)의 하면으로부터 상면의 낮은단부(331a)에 형성된 관통홀(342)까지 관통된다. 이 때, 걸림돌기(330)가 와셔본체(310)의 상면에 경사지게 돌출형성되고 관통홀(342)은 도 3의 (a)에 도시된 바와 같이 와셔본체(310)의 상면에 부분적으로 관통되게 형성된다. The insertion groove 340 receives the magnetic force member 350 therein. The insertion groove 340 extends from the lower surface of the washer main body 310 to the through hole 342 formed in the lower end portion 331a of the upper surface. 3 (a), the locking protrusion 330 is protruded obliquely from the upper surface of the washer main body 310, and the through hole 342 is partially penetrated through the upper surface of the washer main body 310 .

자력부재(350)는 삽입홈(340)에 삽입되어 볼트(100)의 체결시 체결대상(M)에 자력을 인가하여, 와셔(300)와 체결대상(M)의 결합력을 증가시킨다. 이러한 상태에서 볼트(100)에 풀림방향으로 회전력이 작용하면, 볼트머리(110)의 경사면(121)은 와셔(300)의 걸림경사면(331)에 걸리어 풀림방향으로 회전이 방지되고, 결국 볼트(100)의 풀림이 방지된다. The magnetic force member 350 is inserted into the insertion groove 340 and applies a magnetic force to the fastening object M when fastening the bolt 100 to increase the coupling force between the washer 300 and the fastening object M. In this state, when the bolt 100 is subjected to the rotational force in the unwinding direction, the inclined surface 121 of the bolt head 110 is prevented from rotating in the releasing direction by being hooked on the inclined surface 331 of the washer 300, (100) is prevented from loosening.

자력부재(350)는 삽입홈(340)에 삽입되는 링 형태로 형성된다. 여기서, 자력부재(350)의 두께(h1)는 삽입홈(340)의 두께(h2) 보다 작게 형성되어 와셔(300)가 볼트(100)와 접촉결합되기 전의 상태에서는 자력부재(350)가 삽입홈(340)의 상부면에 부착되어 있으므로 자력부재(350)는 와셔본체(310)의 바닥면으로부터 일정거리 이격되게 위치된다.The magnetic force member (350) is formed in the shape of a ring inserted into the insertion groove (340). The thickness h1 of the magnetic force member 350 is smaller than the thickness h2 of the insertion groove 340 so that the magnetic force member 350 is inserted in the state before the washer 300 is in contact with the bolt 100 The magnetic force member 350 is positioned at a distance from the bottom surface of the washer main body 310 because the magnetic force member 350 is attached to the upper surface of the groove 340.

자력부재(350)의 두께(h1)가 삽입홈(340)의 두께(h2) 보다 작게 형성되는 것은 볼트(100)에 와셔(300)가 결합되기 전에는 통상 볼트(100)와 와셔(300)가 혼재되어 있게 된다. The thickness h1 of the magnetic force member 350 is formed to be smaller than the thickness h2 of the insertion groove 340 because the bolt 100 and the washer 300 are normally inserted into the bolt 100 before the washer 300 is engaged It becomes mixed.

이때, 복수개의 와셔(300)가 섞여 있을 때 자력부재(350)가 삽입홈(340)과 동일 두께로 형성되어 와셔본체(310)의 하부로 노출되어 있을 경우 자력에 의해 서로 부착된 와셔(300)들을 분리하는데 어려움을 겪게 된다. At this time, when the magnetic force member 350 is formed to have the same thickness as the insertion groove 340 when the plurality of washers 300 are mixed and exposed to the lower portion of the washer main body 310, the washer 300 ). ≪ / RTI >

따라서, 본 발명의 와셔(300)는 자력부재(350)의 두께(h1)를 삽입홈(340)의 두께(h2) 보다 작게 하여 와셔본체(310)의 하면과 일정높이 이격되게 자력부재(350)가 배치되도록 한다. 이에 따라 도 4의 (b)에 도시된 바와 같이 복수개의 와셔(300,300a)가 직접 맞닿게 배치되더라도 자력부재(350)는 삽입홈(340)의 상부면에 부착되어 있으므로 와셔(300)의 자력부재(350)가 와셔(300a)에 직접 부착되는 것보다는 자력이 작은 것이어서 와셔(300)와 와셔(300a)를 용이하게 분리할 수 있게 된다. The thickness h1 of the magnetic force member 350 is smaller than the thickness h2 of the insertion groove 340 so that the magnetic force member 350 is spaced apart from the lower surface of the washer main body 310 by a predetermined height ). The magnetic force member 350 is attached to the upper surface of the insertion groove 340 even though the plurality of washers 300 and 300a are directly in contact with each other as shown in FIG. It is possible to easily separate the washer 300 and the washer 300a since the member 350 has a smaller magnetic force than that attached directly to the washer 300a.

이때, 자력부재(350)는 삽입홈(340)의 상부면에 위치되므로 도 3의 (a)에 도시된 바와 같이 와셔본체(310) 상면의 관통홀(342) 외부로 일정 높이 노출되게 배치된다. 이 상태에서 볼트(100)를 체결대상(M)에 체결하기 위해 와셔(300)를 중심으로 볼트머리(110)를 회전시켜 볼트(100)를 체결하면 볼트(100)의 결합돌기(120)가 걸림돌기(330)와 밀착되면서 결합돌기(120)의 수직면(123)이 관통홀(342) 외부로 노출된 부분의 자력부재(350)를 하부로 가압하게 된다.
Since the magnetic force member 350 is positioned on the upper surface of the insertion groove 340, the magnetic force member 350 is disposed to be exposed to a certain height outside the through hole 342 on the upper surface of the washer main body 310 as shown in FIG. 3 (a) . In this state, when the bolt 100 is fastened by rotating the bolt head 110 around the washer 300 to fasten the bolt 100 to the fastening object M, the fastening protrusion 120 of the bolt 100 The vertical surface 123 of the engaging projection 120 presses the magnetic force member 350 of the portion exposed to the outside of the through hole 342 downward while tightly contacting the engaging protrusion 330.

이러한 구성을 갖는 본 발명에 따른 풀림방지 볼트조립체(1)를 이용해 체결대상을 체결하는 과정을 도 1 내지 도 6을 참조하여 설명한다. A process of fastening an object to be fastened using the loosening prevention bolt assembly 1 according to the present invention having such a configuration will be described with reference to FIGS. 1 to 6. FIG.

체결대상(M)에 체결되기 전에는 풀림방지 볼트조립체(1)의 볼트(100), 와셔(300)는 서로 함께 또는 별도로 보관된다. 이때, 와셔(300)는 내부에 삽입된 자력부재(350)의 자력 때문에 이웃하는 와셔(300)와 서로 부착되어 있는 상태를 유지하게 된다. The bolts 100 and the washers 300 of the loosening prevention bolt assembly 1 are stored together or separately before being fastened to the object M to be fastened. At this time, due to the magnetic force of the magnetic force member 350 inserted in the washer 300, the washer 300 maintains a state of being attached to the neighboring washer 300.

도 4의 (b)에 도시된 바와 같이 복수개의 와셔(300,300a)는 자력부재(350)의 자력에 의해 삽입홈(340)의 상부면에 부착된 상태를 유지한다. 이 때, 와셔(300)의 상부에 형성된 관통홀(342)를 통해 자력부재(350)는 일정 높이 상부로 노출된 상태를 유지한다. The plurality of washers 300 and 300a remain attached to the upper surface of the insertion groove 340 by the magnetic force of the magnetic force member 350, as shown in FIG. 4 (b). At this time, the magnetic force member 350 is exposed above the predetermined height through the through hole 342 formed in the upper portion of the washer 300.

자력부재(350)는 삽입홈(340)의 상부에 위치하게 되므로 와셔본체(310)의 바닥면과 일정 높이 간격을 유지하게 된다. 따라서, 이웃하는 와셔(300,300a)와 접촉되어 있더라도 자력부재(350)와 이웃하는 와셔(300)와는 상술한 높이 간격만큼 이격됨으로써 자력부재(350)가 이웃하는 와셔(300a)에 직접 접촉하는 만큼의 자력은 미치지 않는다. The magnetic force member 350 is positioned at the upper portion of the insertion groove 340, and thus the magnetic force member 350 is maintained at a predetermined height interval from the bottom surface of the washer main body 310. Therefore, even when the adjacent magnetic member 350 is in contact with the washer 300 or 300a, the magnetic member 350 is spaced apart from the washer 300 adjacent to the adjacent washer 300 by the above-described height interval so that the magnetic member 350 directly contacts the neighboring washer 300a The magnetic force of

이에 작업자는 와셔(300)의 사용을 위해 이웃하는 와셔(300,300a)들을 서로 분리할 때 자력부재(350)가 이웃하는 와셔(300)에 직접 접촉된 상태 보다는 훨씬 적은 힘으로 와셔(300)를 분리할 수 있다. The worker can remove the washer 300 from the adjacent washer 300 by using much less force than when the neighboring washers 300 and 300a are separated from each other by the magnetic force member 350 in direct contact with the adjacent washer 300. [ Can be separated.

와셔(300)를 분리한 후 체결대상(M)의 상면에 와셔(300)를 배치하고 볼트축(130)을 삽입한다. 이후 스패너(미도시)를 이용해 볼트머리(110)를 회전시키면 볼트(100)가 고정너트(N)에 체결되면서 체결대상(M)을 고정한다. After the washer 300 is detached, a washer 300 is disposed on the upper surface of the fastening object M and the bolt shaft 130 is inserted. Thereafter, when the bolt head 110 is rotated using a spanner (not shown), the bolt 100 is fastened to the fixing nut N, and the fastening object M is fixed.

도 5의 (a)에 도시된 바와 같이 초기에는 볼트머리(110)의 결합돌기(120)는 와셔(300)의 걸림돌기(330)의 경사면으로 유입되고, 이어서 걸림돌기(330)에 걸려 결합돌기(120)와 와셔(300)는 함께 회전된다. 5A, the coupling protrusions 120 of the bolt head 110 are initially introduced into the inclined surfaces of the locking protrusions 330 of the washer 300, then engaged with the locking protrusions 330, The projection 120 and the washer 300 are rotated together.

이후, 높은단부(121a)의 가압력에 의해 관통홀(342)의 상부로 노출된 자력부재(350)는 와셔본체(310)의 바닥면까지 하강됨과 동시에 볼트머리(110)는 회전을 멈추고 볼트(100)와 고정너트(N)의 체결은 완료된다. The magnetic force member 350 exposed to the upper portion of the through hole 342 is lowered to the bottom surface of the washer main body 310 by the pressing force of the high end portion 121a and at the same time the bolt head 110 stops rotating, 100) and the fixing nut (N) are completed.

즉, 체결이 완료되면 도 5의 (b)에 도시된 바와 같이 결합돌기(120)의 수직면(123)과 걸림돌기(330)의 걸림수직면(333)이 서로 밀착되며, 자력부재(350) 및 와셔본체(310)의 바닥면은 체결대상(M), 철골 등 자력부재(350)와 부착되는 대상물의 상면에 밀착되어 볼트머리(110)는 더 이상 회전하지 않게 된다. 5 (b), the vertical surface 123 of the engaging projection 120 and the engaging vertical surface 333 of the engaging projection 330 are in close contact with each other, and the magnetic force members 350 and The bottom surface of the washer main body 310 is brought into close contact with the upper surface of the object to be attached with the magnetic force member 350 such as a fastening object M and a steel frame so that the bolt head 110 is no longer rotated.

한편, 도 6은 도 5의 (b)의 A역역의 단면을 확대하여 도시한 단면도이다. 도 5의 (b)와 도 6에 도시된 바와 같이 결합돌기(120)의 낮은단부(121a)가 걸림돌기(330)의 낮은단부(331a)까지 이동하게 되면서 관통홀(342)의 상부로 노출된 자력부재(350) 상부를 가압함으로써 자력부재(350)가 와셔본체(310)의 바닥면까지 하강됨은 당연한 것이다. 6 is an enlarged cross-sectional view of a cross section of the area A in Fig. 5 (b). The lower end portion 121a of the engaging projection 120 is moved to the lower end portion 331a of the engaging projection 330 to expose the upper portion of the through hole 342 as shown in Figures 5 (b) and 6 The magnetic force member 350 is lowered to the bottom surface of the washer main body 310 by pressing the upper portion of the magnetic force member 350. [

즉, 관통홀(342)의 상부로 노출된 부분의 자력부재(350) 상부가 결합돌기(120)의 낮은단부(121a)의 가압에 의해 삽입홈(340)의 하부방향으로 하강되어 도 6에 도시된 바와 같이 와셔본체(310)의 바닥면까지 이동하게 된다. 이 때, 자력부재(350)는 삽입홈(340)의 하부에서 체결대상(M)으로 자력을 부여하여 볼트(100) 및 체결대상(M)의 결합상태가 안정적으로 유지되도록 한다. That is, the upper portion of the magnetic force member 350 exposed at the upper portion of the through hole 342 is lowered in the lower direction of the insertion groove 340 by the pressing of the lower end 121a of the engaging projection 120, And moves to the bottom surface of the washer main body 310 as shown in FIG. At this time, the magnetic force member 350 applies a magnetic force to the fastening object M at the lower portion of the insertion groove 340, so that the state of engagement of the bolt 100 and the fastening object M is stably maintained.

또한, 체결대상(M)에 진동이 발생되어 와셔(300) 및 볼트(100)에 진동이 전달되더라도 와셔(300)는 자력부재(350)와 함께 체결대상(M)에 밀착된 상태에 있으며, 볼트머리(110)는 낮은단부(121a)가 와셔(300)의 낮은단부(331a)의 경사면에 걸리어 회전이 방지되어 결국 볼트(100)의 풀림이 방지된다. Even if vibration is generated in the fastening object M and the vibration is transmitted to the washer 300 and the bolt 100, the washer 300 is in tight contact with the fastening object M together with the magnetic force member 350, The bolt head 110 prevents the bolt 100 from loosening because the lower end portion 121a is prevented from being rotated on the inclined surface of the lower end portion 331a of the washer 300. As a result,

또한, 도 4의 (c)에서와 같이 자력부재(350)에 돌기(351)가 형성되고, 와셔(300)의 삽입홈(340)의 외주연에 돌기(351)에 대응되도록 반경방향 외측으로 돌기홈(341)이 형성됨으로써 자력부재(350)가 체결대상(M)에 자력이 인가되어 부착된 경우에 와셔(300)가 자력부재(350)에 고정되어 와셔(300)만 별도로 회전하는 것을 방지하는 효과가 있다. 즉, 와셔(300)가 겉도는 것을 방지할 수 있다.
4C, protrusions 351 are formed in the magnetic force member 350 and the outer circumferences of the insertion grooves 340 of the washer 300 are radially outwardly corresponding to the protrusions 351 When the magnetic force member 350 is attached to the object to be fastened M by being formed with the protrusion groove 341, the washer 300 is fixed to the magnetic force member 350 so that only the washer 300 rotates separately . That is, it is possible to prevent the washer 300 from being exposed.

이상에서 살펴본 바와 같이 본 발명에 따른 풀림방지 볼트조립체는 볼트머리와 와셔에 형성된 경사면에 의해 볼트가 회전이 방지될 뿐만 아니라 와셔에 형성된 자력부재가 와셔와 체결대상을 결속함으로써 와셔의 회전이 방지되어 볼트의 풀림이 방지된다. As described above, the bolt assembly according to the present invention prevents the bolt from being rotated by the bolt head and the inclined surface formed on the washer, and the magnetic force member formed on the washer binds the washer and the object to be fastened, Bolt loosening is prevented.

또한, 본 발명에 따른 풀림방지 볼트조립체는 체결대상에 체결되기 전에는 자력부재가 와셔의 하부면으로부터 이격되게 배치시키고, 볼트와 너트의 결합시에는 볼트의 수직면이 자력부재를 하강시켜 자력부재가 체결대상에 밀착되게 함으로써, 볼트, 와셔 및 와셔와 체결대상 상호간의 결합력을 향상시킬 수 있다. The bolt assembly according to the present invention is characterized in that the magnetic force member is disposed so as to be spaced apart from the lower surface of the washer before the bolt is fastened to the object to be fastened and the vertical surface of the bolt is lowered, So that the engagement force between the bolt, the washer, the washer, and the object to be fastened can be improved.

이에 의해, 자력부재가 삽입된 와셔가 체결대상에 체결되기 전에는 와셔본체로부터 자력부재가 돌출되지 않고 와셔본체의 상부에 위치하여 이웃하는 볼트, 와셔로부터 와셔가 쉽게 분리될 수 있어 와셔의 분리작업을 용이하게 할 수 있는 효과가 있다.
Accordingly, the washer can be easily separated from the adjacent bolt and washer by positioning the washer main body at the upper portion of the washer main body without protruding the magnetic force member from the washer main body before the washer having the magnetic force member is fastened to the fastening object. There is an effect that it can be facilitated.

한편, 도 7은 본 발명의 다른 실시예에 따른 풀림방지 볼트조립체(1a)의 결합과정을 도시한 예시도이다. 7 is an exemplary view showing a process of assembling the release preventing bolt assembly 1a according to another embodiment of the present invention.

앞서 설명한 본 발명의 바람직한 실시예에 따른 풀림방지 볼트조립체(1)는 볼트머리(110)의 하부와 와셔(300)의 상부가 서로 걸림결합되어 볼트(100)의 풀림이 방지되었다. The release preventing bolt assembly 1 according to the preferred embodiment of the present invention described above prevents the bolt 100 from loosening by engaging the lower portion of the bolt head 110 and the upper portion of the washer 300 with each other.

반면, 본 발명의 다른 실시예에 따른 풀림방지 볼트조립체(1a)는 너트(200)의 하부와 와셔(300)의 상면이 서로 걸림결합되어 너트(200)의 풀림이 방지된다. According to another embodiment of the present invention, the lower portion of the nut 200 and the upper surface of the washer 300 are engaged with each other to prevent the nut 200 from loosening.

즉, 상술한 본 발명의 바람직한 실시예의 볼트머리(110)의 결합돌기(120)가 다른 실시예에서는 너트(200)의 결합돌기(220)로 적용되어 와셔(300)와 걸림결합된다. That is, the coupling protrusion 120 of the bolt head 110 of the preferred embodiment of the present invention described above is applied to the coupling protrusion 220 of the nut 200 and is engaged with the washer 300 in another embodiment.

이러한 본 발명의 다른 실시예에 따른 풀림방지 볼트조립체(1a)는 바람직한 실시예에 따른 풀림방지 볼트조립체(1)와 비교할 때 너트(200), 와셔(300), 체결대상(M) 및 고정볼트(100a) 순의 체결에 의해 너트(200)까지 결합력이 적용되고, 고정볼트(100a) 뿐만 아니라 너트(200)에 회전력이 적용하더라도 고정볼트(100a)의 풀림이 방지될 수 있다.
